Unfortunately, I have failed to reproduce this issue locally.

Can you please share which version of GroupDocs.Viewer you’re using and what environment you’re running the app? In case you could share the code snippet it would also help to reproduce the issue.

my system
Windows server 2019
Visual Studio 2022
.Net Framework 4.5
Groupdocs.Viewer 22.5.0.0
Thank you
